摘　　要：提出了一种新型紧凑单馈的双频段天线,天线采用单层微带馈线和开口矩形框的接地板结构,分别印制在介质板的两侧。天线的面积只有13 mm×22 mm。天线的工作中心频率分别为2.45 GHz和5.25 GHz,同时,运用HFSS10电磁仿真软件对影响工作中心频率的参数进行了分析。最后制作出实物,并且对其进行测试,测试结果与仿真结果基本吻合。所提出的天线具有小型化和双频段的特性,在无线局域网通信中有很好的应用前景。A novel compact single-feed dual-frequency patch antenna is proposed in this paper. Monolayer microstrip-fed and split- rectangle frame are adopted and printed on the opposite sides of substrate in this antenna. The area of this antenna is only 13 mmx 22 mm. The operating frequencys are 2.45 GHz and 5.25 GHz. Simulated in the EM simulation software HFSS 10 and the param- eters that affect the operation frequencies are analyzed and researched. Lastly, the antenna is fabricated and measured, and the measured results are in good agreement with the simulated results. The antenna proposed in this paper has the characteristics of miniaturization and dual-band,which is also suitable for WLAN applications.
